The shaft 121 is made of steel material of SUS440, and has a first stepped portion 1212 and a second stepped portion 1213. Wherein the first step 1212 is adjacent to the bearing connection 1211 and the second step 1213 is remote from the bearing connection 1211. The outer combined plate 124 may be a circular plate made of SUS304 steel, and is sleeved on the shaft 121 and attached to the first step 1212; the inner combined plate 125 may be a circular plate made of SUS304 steel, and is sleeved on the shaft 121 and attached to the second step 1213.

Wherein the inside composition plate 125 is located in the roller body 11, and an outer surface 1241 of the outside composition plate 124 adjacent to the bearing connection 1211 is flush with the end surface of the roller body 11.

It should be noted that a first fixing unit 31 is disposed between the outer surface 1241 of the outer assembly plate 124 and the roller body 11, a second fixing unit 32 is disposed between the outer surface 1241 of the outer assembly plate 124 and the shaft 121, and a third fixing unit 33 is disposed between an inner surface 1242 of the outer assembly plate 124 opposite to the outer surface 1241 and the shaft 121.
